SPECIFICATION forming part of Letters .Patent No. 686,975, datedNovember 19, 1901.

Application filed April 22, 1901.

.T0 all whom it may concern.-

Be it known that I, HAROLD KELLY, a citizen of the United States,residing at Biddeford, in the county of York and State of Maine, haveinvented certain new and useful Improvements in Spindle-Plumbs; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates toimprovements in spindle-plumbs or instruments bywhich the perpendicularity of spin ning-spindles may be determined.

In the art of spinning as at present practiced the spindles are mountedupon a rail, above which is a second rail bearing the spinning-rings,said second rail having vertical movement relative to the first-namedrail. Thespindleis removably mounted inaspindlecase which extends downthrough the lower rail and is clamped thereto by a nut impinging againstthe bottom ofthe rail. In practice itis not feasible to stop thespindles while they are being plumbed, and the problem to be solved isto plumb the spindle quickly and easily while the spindle is running.This is easily and quickly done by means of the improved plumbing deviceshown in Letters Patent No. 519,716, granted to John P. Kelly May l5,1894, the operation of which is clearly described in said LettersPatent. While this furnishes a ready means of plumbing the spindle, itaffords no means of determining when the spindle is plumb; and theobject of the present invention is to provide a device which may bereadily applied to a running spindle, s o as to show when the spindle isplumb. It is not intended to limit its usc to any particular means forplumbing spindles, and it is applicable whether the said Kellyplumbing-disks or other means for plumbing the spindle are used. It alsoobviates the ne. cessity of moving the second rail up and down.

In the drawings herewith accompanying and making a part of thisapplication, Figure 1 is a central sectional view of my improvedspindle-plumb, the leveling instrument being shown in elevation. Fig. 2is a detail plan view showing means for clamping the bobbin to therotating disk. Fig. 3 is a detail perspective showing the means ofadjusting the Serial No. 56.872. (No model.)

clamping device to iit bobbins of diierent sizes; Fig. 4 is a centralsectional View of my device in an embodiment adapted to be applieddirectly to the spindle, thus obviating the use of the bobbin, thelevel-containing box being omitted. Fig. 5 is a top plan view showingthe plumbing device.

Same letters of reference refer tolike parts.

Referring now to said drawings, A represents the spindle-supportingrail, B the spindie-case, set in the rail and being clamped thereto by anut C, adapted to turn against the bottom of the rail in the usualmanner, and D the extended base of the spindle-case, adapted to restupon the top of the rail. It is customary to plumb the spindle-case, andthereby the spindle, by inserting thin disks lA', of paper or othermaterial, between the said rail and the base of the spindle-case.

In the embodiment of my invention shown in Fig. l, E shows a box havingfor convenience a removable bottom F, in Which is a revolubly-mounteddisk G, and in order that the same may rotate with as little friction aspossible the disk is mounted upon ball-bearings, which may be arrangedin any suitable manner. As shown, both edges of the disk are beveled, asseen at I-I H, and the ballbearings I travel upon ways formed in the topof the box and in the inner face of the bottom, as seen at J and K,respectively; but I do not thereby intend to limit myself to anyparticular way of mounting said revoluble disk. The bottom may besecured to the box by means of threaded screws L, extending through thebottom into the walls of the box, and in order that the bottom may havea yielding and adjustable fit with ren spect to the ball-bearings saidscrews may be surrounded with coil-springs B', whereby the bottom may beadjusted relative to the box by Ameans of said screws. The bobbin X,which lits over the spindle, has the usual disk X', the diameter ofwhich should be slightly less than the inside diameter of a spinningring(not shown) and serves to show IOO It is rigidly secured to therevoluble disk in any convenient manner. Inasmuch as the diameters ofbobbins vary somewhat I have provided means for securing an adJustablefit, which consists of a tapering chuck M, adapted to enter a circularhole M in said revoluble disk and be locked thereto against rotation bymeans ofV ears N, tting into recesses 0 in the disk, adapted to receivethem. The chuck has a series of vertical cuts O extending into it fromthe bottom and is adapted to be compressed to bind against the body ofthe bobbin by means of a threaded nut P.

On top of the box is mounted the plumbing instrument, which in the caseshown in Fig. l consists of two spirit-levels S S, extending at rightangles to each other. The plumbing instrument may be set in a box Y,made integral with or secured to the top of the box E and protected by atransparent cover Q, if desired. Secured to the outside of the box is anarm R, adapted to bear against some stationary part of thespinning-frame and adapted to hold the box against rotation.

The operation of my device as thus embodied is as follows: The bobbincarrying the plumb is placed upon the running spindle. The nut is thenloosened. The spindlecase, which contains the bearings for the spindle,is then tipped or adjusted in any convenient manner until the plumbinginstrument shows that the spindle is plumb. The case is then set finallyin its adjusted position by tightening up the nut C. The bobbin andplumbing instrument are then removed to the next spindle needingplumbing, and so on through the whole frame, thus rendering itunnecessary to stop the operation of the frame or the running of any ofthe spindles therein.

Instead of using the separate bobbin upon which to mount my improvedplumb a hollow case P may be permanently secured directly to therevoluble disk C, adapted to receive the top of the spindle and torotate with the spindle and with the disk, as seen in Fig. 4. The case Pmay have vertical slots U therein, and adapted to register up and downin said case is an interiorly-tapering hollow sleeve T, which fits thehead of the spindle. This sleeve can be adjusted vertically and can beheld in any desired place by means of set-screws Q, passing through saidslots and engaging said sleeve. The lower extremity of said case isexternally screw-threaded, as seen at S', and has a threaded nut Uthereon, which serves the same purpose as the disk X' in the formerTease. The construction of the other parts of the device when embodiedin this form may be substantially the same as that hitherto described.Its operation is substantially the same as in the former case.

Having thus described my invention and its use, I claiml. In aspindle-plumb, two members revo-v lubly connected together, one adaptedto be mounted upon and rotate with a running spindle and the othercarrying a plumbing instrument and adapted to remain stationary.

2. In a spindle-plumb, two members revolubly connected together, oneadapted to be mounted upon and rotate with the spindle, the otheradapted to carry a plumbing instrument and means for preventing itsrotation with the first member.

3. In a spindle-plumb, a suitable inclosing box carrying on top thereofthe plumbing instrument, a disk mounted therein and adapted to rotateindependently thereof, on antifriction bearings interposed between saiddisk and said box, a bobbin, means for rigidly securing said bobbin tosaid disk and means for preventing the rotation of said box.

In testimony whereof I affix my signature, in presence of two Witnesses,this 15th day of April, 1901.

HAROLD KELLY.
